Study on dynamic response of moving tank under the action of temperature field

A three-dimensional numerical model of the tank’s barrel was established using the finite element method, and dynamic process of thermal load boundary changing with projectile movement was defined. The evolution of the temperature distribution of the barrel under the firing conditions of the first projectile was obtained through numerical calculations. Furthermore, a multi-body dynamics software was used to build a shooting model for tank with a temperature field, the effects of the temperature field on the vibration of the barrel and the attitude of the projectile were studied and calculated, finally, the regular pattern of the stress of the barrel under the temperature field was analyzed. The simulation results of this model show that temperature field has a negligible effect on the barrel vibration and the projectile attitude
